W H E E L- H U B SPECIFICATION forming part of Letters Patent No. 469,235, dated February 23,1892.

Application tiled October 1, 1891. Serial No. 407,462. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JAMES EDWARDS, a citizen of the United States,iresiding at Peru, in the county of La Salle and State of Illinois,

have invented certain new and useful Ilnprovements in Wheel-Hubs, of which the following is a specification, reference being had -to the accompanying drawings, in which- Figure lis a central vertical section. Fig. 2

4ro is a plan view of the exterior of the journal- In the drawings, a indicates the hub of a wheel, which is adapted to receive a sleeve h, which forrnsa box to receive an axle-spindle. The exterior of that part of the box b which tits into the hub a is preferably provided with 3o fins c, adapted to engage the inner surface of the hub in the usual manner. The inner end of the box b is provided with a collar d, adapted to engage the inner edge of the hub to act as a stop for the h nb. The box b is provided with one or more longitudinal channels or grooves f, which are so placed as to be covered by the hub when it is placed upon the box and terminate at a point Linder the outer edge of thehub, as best shown in Fig. l. A recess gis provided at a suitable point in each channel, preferably near its inner end.

The hub a is provided with a channel 7L on its inner surface, which is substantially similar to the channel f, except that it is not provided with the recess g. The channel h is so placed that it will register with the channel f, and the number of channels in the hub is equal to the number in the box b.

j indicates a key, which is adapted to lie in 5o the space formed by the two channels f and 7L. The inner endet the key is bent to form an extension 71s, adapted to enter the recess g, as best shown in Fig. 1, and the key is made of such shape as to tit snugly in its place. I prefer to make the channels f and h semicircular and to use a piece of wire for a key, as this construction is more simple and inexpensive. The length of the key j is such that it extends a short distance beyond the outer 6o edge of the hub.

To secure the hub in place upon the box b the key j is first placed in the channel f, its extension 7c tting the recess g. The hub is then placed upon the box in such posit-ion that the keyj will t in the channel h. The outer end of the key is then swaged or bent upon the outer rim of the hub, as best shown in Fig. l. The hub and box will thereby be firmly secured together and the withdrawal 7o of the hub from the box is efectually prevented. The key also prevents turning of the hub on the box. This method of securing the hub upon the box is more particularly adapted for use with metallic Wheels; but it may be applied to any other hubs having separate journal-boxes.

That which I claim as new, and desire to secure by Letters Patent, is

l. The combination, with a hub having a 8o channel 7L, of an axlebox having a channel f, adapted to register with the channel h, and a key adapted to be secured in said channels to firmly secure the hub and box together, substantially as described.

2. The combination, with a hub a, having a channel h, and a box Z), adapted to lit into said hub and having a channel f and recess g, of akey j, adapted to fit into said channels, said key having' a projection 7o, adapted to 9o enter the recess g, the outer end of said key being adapted to be swaged or bent upon the hub, substantially as described.

JAMES EDWARDS.
